Separation of the pigment-lipid esters of Xanthomonas juglandis (campestris) in a silica gel G:celite 545 column yielded 4 bands. Two of these bands, ester #1 and #2, make up over 95% of the mixture. Analysis of the four pigments indicate that three are phospholipids and that the phosphate accounts for about 3-4% of the weight of each of the two major esters.

The lecture recital, given on April 18, 1983, began with biographical background that suggests the influences on the compositional development of both the composer, Charles Widor, and the poet, Paul Bourget, of the Chanons de mer. Songs were chosen to examine the characteristics that not only enhance Widor's poetic rendering, but impart to the Chansons de mer the more intellectual appeal often desired in today's concert repertoire.

The purpose of this study is to trace the role of music and music education in Abilene, Texas, from 1881 to 1911. The research presents historical data relative to five categories: Educational music, cultural music, religious music, music of the vernacular, and music merchandising. The study utilizes personal interviews, newspaper files, city directories, local histories, photographs, city and county documents, school documents, minutes of public school board meetings, minutes of meetings of churches, school catalogues, articles in journals, unpublished works, and published books.

In Morte Nobilis is a cantata for chamber orchestra and three vocal soloists, and is approximately seventeen minutes in duration. Each of the three movements features a different vocal soloists (soprano, baritone, or tenor) and each movement concerns a specific Christian martyr. Texts for In Morte Nobilis are extracted from the writings and biographies of the martyrs. Each text gives the listener some insight as to how each martyr faced their death with courage and unwavering faith. The music of In Morte Nobilis gives additional insight as to what these martyrs faced. This is accomplished through a building and release of tension and dissonance, as well as some use of non-standard vocal technique.

Music for Katurah is scored for string quartet, flute, alto flute, soprano saxophone, bass clarinet, piano, and two percussion with total duration of approximately nineteen minutes. The work has three movements and uses spatial as well as standard notation. Each movement begins softly, builds gradually to a highpoint, and returns to the soft beginning. Timbral exploration and improvisation are prominent features in this piece. Also, through the use of spatial and standard notation, the piece combines strict rhythms and free rhythms.

Polysonisisms is a one-movement work for symphonic wind ensemble and electronic tape of approximately eleven minutes' duration. The title conveys two ideas: many sounds and processes. Pitch use is based on a system for calculating the potential dissonance of four-note sets. From this system all linear and vertical pitch materials are derived.

The role of protein kinases in modulating cell proliferation was examined. Studies characterized the regulation of cell proliferation by adenosine 3':5'-monophosphate-dependent protein kinase (cA-PK). Calcium/calmodulin-dependent myosin light chain kinase (MLCK) was isolated and examined as a potential substrate regulated by cA-PK in the rapidly proliferating.

The effect of adding pure cultures of Azotobacteraceae ad triacontanol to orchid protocorms and seedlings was studies to determine if significant enhancement of various growth parameters would result in axenic cultures of orchids.

This thesis examines the rhetorical dimensions of oral interpretation. A group interpretation script entitled "A New Prayer for Peace" was compiled and rehearsed. Two public performances were given to audiences in the Roman Catholic Diocese of Fort Worth (Texas). The audience members were surveyed to solicit subjective reaction.

Human Alpha 1-acid Glycoprotein (AAG) was analyzed quantitavely and qualityatively for differences which could be associated with oncogenesis. Levels of seru, AAG were elevated in most mlignancies, particularly in malignant melanomas, malignant myelomas, and in solid tumors of the lung, kidney, colon, or other organs.

Thin layer chromatography and high performance liquid chromatography were used to compare pigments of the wild type streptomycin resistant strain of C. poinsettiae with those of mutants derived from it. Possible biosynthetic pathways in carotenoid biosynthesis of the wild type were postulated on the basis of observed blocks in pigment synthesis.
